Clinical trials for primary prevention and early intervention in preclinical AD require measures of functional capacity with improved sensitivity to deficits in healthier, non-demented individuals. To this end, the Virtual Reality Functional Capacity Assessment Tool (VRFCAT) was developed as a direct performance-based assessment of functional capacity that is sensitive to changes in function ac...

The state-independent (SI) and state-dependent (SD) path restoration schemes for self-healing networks are studied in this paper. The integer programming (IP) formulations for the spare capacity allocation and restoration flow assignment are first presented. Based on the optimal IP solutions, the SI and SD restoration schemes are then compared quantitatively in terms of spare capacity requireme...

This article aims to redefine the concept of Thirdspace and make a trilateral relationship between the three concepts of real space, virtual space and the user. To do so, not only the concept of Thirdspace has to be redefined, but also a new understanding of virtual space as a relatively independent space is required. This three-sided relation requires a new understanding of the relationship be...

Background: According to the situation of education in Iran it is clear that over the years, there has been no successful attempt to identify related challenges and problems to development and implementation of virtual training. In this regard, the effect of this type of training influenced by the role of hidden curriculum of education in the country.   Based on this, current study has investig...

Virtual nesting is a popular capacity control strategy in network revenue management. (See Smith et al. [36].) In virtual nesting, products (itinerary-fare-class combinations) are mapped (\indexed") into a relatively small number of \virtual classes" on each resource (°ight leg) of the network. Nested protection levels are then used to control the availability of these virtual classes; speci ̄ca...

background: the i-space is a radiological imaging system in which computed tomography (ct)-scans can be evaluated as a three dimensional hologram. the aim of this study is to analyze the value of virtual reality (i-space) in diagnosing acute occult scaphoid fractures.   methods: a convenient cohort of 24 patients with a ct-scan from prior studies, without a scaphoid fracture on radiograph, yet ...

the purpose of this study was to evaluate the rate of using standards of designing electronic courses in educational contents of state-virtual universities in iran. the method of the study was a descriptive-survey one. the statistical population was the educational content of electronic courses in state-virtual universities such as university of science and technology, and shiraz university. da...
